Abstract
Description
本出願は、2022年6月17日出願の日本出願第2022-097768号に基づく優先権を主張し、前記日本出願に記載された全ての記載内容を援用するものである。
特許文献1によると、荷役の開始時刻及び終了時刻を特定することはできるものの、車両の作業施設への到着時刻及び作業施設からの出発時刻を正確に特定することができない。
本開示によると、車両の目的地への到着時刻及び目的地からの出発時刻を正確に特定することができる。
最初に本開示の実施形態の概要を列記して説明する。
(1)本開示の一実施形態に係る車両運行管理システムは、車両の位置、当該位置を前記車両が通過した時刻、及び当該時刻における前記車両の速度を示す走行実績情報を取得する走行実績情報取得部と、前記車両の目的地の位置を示す目的地情報を取得する目的地情報取得部と、前記走行実績情報及び前記目的地情報に基づいて、前記車両の前記目的地への到着時刻、及び前記車両の前記目的地からの出発時刻を決定する決定部とを備える。
以下、本開示の実施形態について、図面を参照しながら説明する。なお、以下で説明する実施形態は、いずれも本開示の一具体例を示すものである。以下の実施形態で示される数値、形状、材料、構成要素、構成要素の配置位置および接続形態、ステップ、ステップの順序などは、一例であり、本開示を限定するものではない。また、以下の実施形態における構成要素のうち、独立請求項に記載されていない構成要素については、任意に付加可能な構成要素である。また、各図は、模式図であり、必ずしも厳密に図示されたものではない。
図1は、本開示の実施形態に係る車両運行管理システムの全体構成を示す図である。
車両運行管理システム1は、車両5の運行管理を行うシステムであり、具体的には、車両5の目的地である荷物の配送先への到着時刻と、配送先からの出発時刻とを決定するシステムである。車両運行管理システム1は、運行時刻分析装置3と、車両5に設置された車載端末5Aとを備える。
図2は、車載端末5Aの構成を示すブロック図である。
車載端末5Aは、通信部51と、位置特定部52と、メモリ53と、プロセッサ54と、バス55とを備える。
通信部51は、外部の装置と無線により通信を行う。
走行実績情報は、車両5に搭載された車載端末5Aの端末ID、車両5の位置、車両5の当該位置の通過時刻、車両5の速度及びセンサ情報を含む。
バス55は、通信部51、位置特定部52、メモリ53及びプロセッサ54を相互に接続する。
図4は、運行時刻分析装置3の構成を示すブロック図である。
運行時刻分析装置3は、通信部31と、メモリ32と、プロセッサ33と、バス34とを備える。
通信部31は、外部の装置と、無線又は有線により通信を行う。
配送先情報36は、配送先を識別するための配送先IDと、配送先住所と、配送先位置とを含む。配送先位置は、(緯度,経度)の組により表される。
運行時刻情報37は、車両5に搭載された車載端末5Aの端末ID、車両5の位置、車両5の当該位置の通過時刻、及び車両5の到着及び出発の別を示す情報を含む。
バス34は、通信部31、メモリ32及びプロセッサ33を相互に接続する。
次に、運行時刻分析装置3による配送先への到着時刻及び配送先からの出発時刻の決定方法について説明する。
S_CNTは、車両5の配送先での滞在時間を示す。
通信部31がデータを受信すると(ステップS3においてYES)、走行実績情報取得部38は、受信したデータに含まれる走行実績情報から、車両5の位置(L)、車両5の位置(L)の通過時刻(T)、車両5の位置(L)における速度(SP)、及びセンサ情報(S)を取得する(ステップS4)。走行実績情報の例は、図3に示した通りである。
上述の実施形態では、運行時刻分析装置3が取得の対象とするセンサ情報は、加速度センサで計測された車両5の加速度であるとした。ただし、センサ情報は、車両5の加速度に限定されるものではない。
上記の各装置を構成する構成要素の一部または全部は、1または複数のシステムLSIなどの半導体装置から構成されていてもよい。
また、上記各装置は、複数のコンピュータ又は複数のプロセッサにより実現されてもよい。
さらに、上記実施形態および上記変形例の少なくとも一部を任意に組み合わせてもよい。
